The coordinates of point a are 30 units of x and 70 units of y. the coordinates of point b are 28 units of x and 76 units of y. with x on the horizontal axis and y on the vertical axis, the slope of the line between points a and b is

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

Solve the system of equations. y= 2x y= x^2 - 15
